IMO, Opal should be a 3-of, if you are not running the Disciple combo with ravager. As having 2 copies of the opal in your hand will be a waste.
-1 Tidehollow Sculler, -1 Master of Etherium, -1 Mox, -1 Drum
+1-2 Etched Champion, +3 Tezzeret, Run 3-4 Pests
As of the mana base:
3 Seat of the Synod
3 Vault of Whispers
4 Darksteel Citadel
3 Glimmervoid
Because you're not running any white spells other than Tidehollow and Tezz anyway. But, if you want to have white sources, -2 Citadels +2 Ancient Den.
Hope this helps :)
